Draught-proofing for Stevenage properties
We cover Stevenage and the SG1 postcode district, including nearby Hitchin, Letchworth Garden City and Welwyn Garden City. It is about 12 miles north-east of St Albans.
We check ventilation as carefully as insulation in Stevenage homes, because both matter for keeping a house dry. In Stevenage homes this is often done on the same visit as a cavity fill, which saves a second trip.
For regulations, if cavity wall insulation follows in Stevenage, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England
In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

Ventilation still matters
Trickle vents, air bricks and extractor fans are there for a reason. We seal accidental gaps, not the ventilation your home needs to keep condensation down.
